To start a diesel generator in winter, follow the following steps:
First, use "0" diesel with low freezing point as fuel;
Second, use hot diesel. water Preheat diesel and engine oil;
The third is to add hot water at about 70℃ as cooling water and preheat it while adding it.
When using a diesel engine in winter, you should pay attention to the following points:
1. Under low temperature conditions, diesel has high viscosity and poor fluidity, which will lead to poor atomization, unstable operation of the diesel engine and even There is an interruption in fuel supply. In winter, therefore, diesel fuel should be used that is fundamentally suitable for the ambient temperature.
2. At lower temperatures, engine oil viscosity increases, increasing thehas resistance to rotation of the crankshaft. When starting the diesel engine when the battery voltage remains unchanged, the diesel engine can be started by increasing the power. If conditions permit, winter engine oil can be used.
3. When the ambient temperature is about -35 degrees, after starting the diesel engine, if cold water is added to the water radiator, the cold water will enter the radiator and freeze immediately because the temperature is too low. Therefore, in areas where the ambient temperature is low, it is necessary to add antifreeze suitable for the ambient temperature into the radiator to prevent the body, radiator and water pump from freezing and cracking.
4. In areas with lower temperatures, the battery electrolyte density should be increased appropriately according to temperature changes. At the same time, due to the grande starting resistance, the battery discharge current increases. At this time, the charging generator regulator should be adjusted appropriately to increase the charging current.
5. When starting the diesel engine in winter, it is best to add hot water to the radiator. It is never allowed to use a blowtorch or open flame to heat oil to reduce the viscosity or resistance of the oil. oil. The consequences of this will lead to deterioration of the engine oil and the formation of oil gum blocks in the combustion zone. Additionally, the oil pan gasket will age and deteriorate easily.
